Specification of Letters Patent.

Patented June 4, 1912.

To all whom t may concern:

Be it known that I, JAMES J. MURPHY, a citizen of the United States, residing at Terryville, in the county of Litcheld and State of Connecticut, have invented a newv and useful Improvement in Suit-Case Locks; and I do hereby declare the following, when taken in connection with the accompanying in edge elevation of the lock without the hasp. Fig. 3 a detached view in inside elevation of the sliding escutcheon of the lock, showing the dust-guard in its closed position over the key-hole. Fig. 4 a view of the sliding escutcheon in horizontal section on an enlarged scale, on the line a-b of Fig. 3. Fig. 5 a broken view on an enlarged scale in horizontal section on the line 0-0Z of Fig. 1, showing the lock stripped of its tumblermechanism, and with the dust-guard in its closed position. Fig. 6 a similar view showing the dust-guard in the open position into which it is moved by the insertion of the key. Fig. 7 a detached reverse view in elevation, of the retaining-,disk used in mounting the pivotal dust-guard in the sliding escutcheon.

My invention relates to an improvement in that class of locks known to the trade as suit-case locks, but now very extensively used on automobile trunks, the object being to provide such locks with cheap, reliable and eective dust-guards to prevent the entrance of dust into them through their keyholes, whereby they are particularly adapted for use on automobile trunks which require their fittings of every description to be as near to dust-proof as it is possible to make them.

With these ends in view, my invention consists in a lock having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a pivotal, leaf-like dustguard 2 formed upon its inner edge with a fold or knuckle -3 receiving a long pintle 4 the ends of which have bearing in housings 5 and 6 struck up from a retaining-disk 7- located within the circular, cup-like sliding escutcheon 8 of the lock and bearing upon the inner face of the said escutcheon. The said disk 7 is cut away'to form an opening 9 for the reception of the said guard 2 which occupies and practically fills the said opening 9 when the guard is in its closed position. The housings 5 and 6 of the disk 7 are not, as shown in Figs. 4 and 7, closed, but the pintle 4 isheld in place by the combined action of the said disk 7 and the inner face of the outer wall of the escutcheon 8.

As shown in Fig. 3, the knuckle 3 is cut away for the application to the pintle of a helical spring 10 arranged to exert a constant effort to close the guard 2 and hold the same in its closed position.

The sliding escutcheon 8 rests and slides upon a bearing-disk 11 corresponding to it in diameter and permanently fastened to the case-plate 12 which is secured to the body of the suit-case or trunk 13 by means of rivets 14 and formed with an opening 15 for the reception of the eye or perforated lug (not shown) upon the inner face of the hasp 16 which is hinged to a hasp-plate 17 secured by rivets 18 to the cover of the suitcase or trunk 19, all of the parts last mentioned being of ordinary construction.

The bearing-disk 11, aforesaid, is cut away as at 20 to afford clearance for the guard 2 when the same is swung open by the key, as well as to aord clearance for the arms 21 by means of which the escutcheon 8 is supported and connected with the sliding bolt 22. A key-hole 23 in the bolt 22 is alined with the key-hole 24 in the escutcheon 8, the key-hole 24 being normally closed by the dust-'guard 2.

On accountof the cup-like form of the sliding escutcheon 8 and the thickness of the bearing-disk 11, I secure ample room for the swinging of the pivotal guard 2 which is carried back and forth with the escutcheon 8 as the same slides laterally on the disk 11 to engage the bolt with, and disengage the bolt from the lug or eye on the inner face of the hasp.

I am aware that dust-guards arranged on the inside and on t-he outside of locks is not broadly new, but I am unaware that a dustguard has ever been applied to a suit-case or trunk lock of the characterdescribed.

of a retaining plate located Within the saidescutcheon, bearing upon the inner face thereof and 'formed with an opening, and a pivotal dust-guard located in the opening of the said plate and held in place thereby, and normally closing the key-hole in the escutoheon.

kIn testimony whereof, I have signed this specification in the presence of two subscrlbing Witnesses.
